Punching ShearShear Reinforcement SteelUltra High Performance ConcreteSteel FiberBEHAVIORExtensive studies have focussed on the issue of the failure of punching shear in flat slabs and ways to strengthen it internally, externally and the importance of this structure (flat slab), and the danger of ...
For this purpose, first, the shear response of a slab鈥揷olumn assembly failing in brittle punching shear under ambient temperature, chosen from the literature, was captured and, subsequently, sequential coupled thermomechanical analyses were carried out using the finite-element software ATENA. ...
punching shear 1.Theshear stresscalculated by dividing the load on a column by the product of its perimeter and the thickness of the base or cap, or by the product of the perimeter taken at one-half the slab thickness away from the column and the thickness of the base or cap. ...
Punching shear at the slab-column connections is one of the most common failure modes in these systems, as punching shear creates a local brittle failure that might lead to a progressive collapse of the entire structure. Previous research has found that the use of UHPFRC can enhance the rigidit...

(xandyaxes of slab plan) and then mounting the external bars (sticking) in one direction and FRP in EBROG (externally bonded reinforcement on groove) method in another direction. The results showed the great efficiency of the method so that the punching shear capacity of strengthened samples ...
Punching shear is the most important problem in flat slabs, which usually required reducing the self-weight of the slab. A lightweight concrete as well as the bubble deck technology were used to allow for lighter self-weight of the structure. This study aims to investigate the use of lightwe...
Punching Shear Capacity of RC Slab by Applying Limit State Design Method In many cases where a reinforced concrete (RC) slab directly supports the wheel load of large-sized vehicles, the static strength of the slab is generally evaluated as punching shear capacity. Given the situation, this stud...
Underground parking structures often consist of flat slabs connected by columns, for which punching shear is often the most critical design criterion. In fire conditions, the punching load can increase due to restraint of the thermal curvature of the slab or due to the expansion of the columns....
Flat slabSteel fiberPunching shearFailure loadFourteen slab-column connections are tested to failure and categorized in two phases. The first "Phase I" consisted of testing ten interior square slabs axially loaded. The second "Phase II" consisted of testing four specimens under eccentric loading to...
